The WORX WG163 dominates budget trimmers with dual 20V batteries delivering 40 minutes of continuous runtime. Its 90° pivoting head converts from trimmer to edger in seconds, while the 5.5-pound frame reduces fatigue during extended yard work. This is the only sub-$50 trimmer that handles thick weeds without bogging down.

Tool-free adjustments set the WG163 apart—twist the shaft to change height, tilt the head for slopes, or rotate for edging. The automatic line feed system actually works, dispensing exactly ¼-inch when needed. For cordless freedom under $50, nothing else comes close.

Two batteries included for uninterrupted work
90° pivoting head for clean edging
Lightweight at 5.5 pounds
Automatic line feed that works reliably
Quick conversion from trimmer to edger

Buyer's Guide

What to Look for in a String Trimmer

Power Source

Corded trimmers offer unlimited runtime for small yards. Cordless models provide freedom of movement but require battery management. Under $50, 20V-21V lithium batteries deliver adequate power for most lawns.

Battery Capacity

Look for 2.0Ah minimum; 4.0Ah batteries double runtime. Dual battery packs let you work while one charges. Runtime varies from 20-45 minutes depending on voltage and weed thickness.

Cutting Width

12-inch swaths suit precision work and tight spaces. 14-inch widths cover ground faster on open lawns. Wider isn't always better—narrower heads maneuver around obstacles easier.

Weight & Balance

Sub-6-pound trimmers reduce arm fatigue during extended use. Look for adjustable shafts to match your height. Well-balanced models keep the cutting head level without constant correction.

Line Feed System

Auto-feed systems advance line automatically but can waste spools. Bump-feed gives manual control. Under $50, auto-feed dominates; test reliability before committing to a brand.

Versatility Features

2-in-1 trimmer/edger combos pivot heads 90° for clean borders. Adjustable poles accommodate different user heights. Metal blade compatibility handles brush beyond grass trimming.

Our Testing Process

How We Test Power Tools

⏱️

Runtime Test

We ran each trimmer continuously on standard grass until batteries depleted, measuring actual minutes versus manufacturer claims.

⚡

Cutting Power Test

Tested on dense weeds, thick crabgrass, and light brush to evaluate motor performance under load and resistance to bogging down.

🔄

Maneuverability Test

Navigated around trees, fence posts, and garden beds to assess pivot head range, weight distribution, and ease of direction changes.

🧵

Line Feed Test

Measured line advancement consistency, waste, and jam frequency during normal operation. Evaluated spool loading difficulty.

🔌

Battery Charge Test

Timed full charge cycles from empty and measured how charge times impact workflow with single versus dual battery systems.

💪

Ergonomics Test

Multiple testers of different heights used each trimmer for 30 minutes, rating grip comfort, vibration, and fatigue levels.

Frequently Asked Questions

Power Tools — FAQ

Can a string trimmer under $50 handle thick weeds?

Yes. Models with metal blades or 6.5-amp corded motors cut through thick vegetation. For cordless, 20V+ systems manage normal overgrowth but struggle with saplings.

How long do budget trimmer batteries last?

2.0Ah batteries provide 20-30 minutes of continuous use. 4.0Ah packs extend runtime to 40-50 minutes. Expect 2-3 years of battery life with proper storage.

Are corded trimmers better than cordless under $50?

Corded trimmers offer unlimited runtime and more power for the price. Cordless provides mobility convenience. Choose corded for yards under 100 feet from outlets.

What's the difference between auto-feed and bump-feed?

Auto-feed advances line automatically when it gets short. Bump-feed requires tapping the head on ground to release line. Auto-feed is more common in budget trimmers but can waste line.

Can I edge my lawn with these trimmers?

Most models here are 2-in-1 trimmer/edgers. Look for 90° pivoting heads that rotate for clean edge cuts along driveways and sidewalks.

How do I maintain a budget string trimmer?

Clean debris from the head after each use. Store batteries indoors during winter. Keep line spools dry. Lubricate pivot points monthly with light oil.

Final Verdict

🏆 Bottom Line

The WORX WG163 stands alone as the best string trimmer under $50, delivering cordless freedom, dual batteries, and proven pivoting-head design that outperforms everything in its price class.

Homeowners with yards under 1,000 square feet can save more with the corded BLACK+DECKER, while those needing heavy brush clearing should invest in the metal-blade model for serious cutting power.
